Description

A kind of shot-blast apparatus electric control system
Technical field
The present invention relates to shot-blast apparatus Electrical Control Technology field, specifically a kind of shot-blast apparatus electric control system.
Background technology
The control system of shot-blast apparatus is mainly made up of ramming head motor, recovery blower fan, lifting motor, helical feed motor, separation vessel motor, leakage sand valve, carrier chain, total electric control system.Because the ball blast control system of prior art cannot detect Workpiece length, the ball blast actual job time is according to the maximum sized activity duration of equipment design, the ball blast actual job time is much larger than effective operation time, and in the ball blast stand-by period, all motors are opening, equipment is for a long time in light condition, energy consumption waste is large, and service life of equipment is short, and the consumption of ball material is large.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of shot-blast apparatus electric control system, make the effective operation time of shot-blast apparatus motor reach the more than 85% of actual job time, eliminate the motor idle running in the stand-by period, thereby promote the Shot Blasting System life-span, reduce the consumption of energy consumption and ball material.
The present invention realizes with following technical scheme: a kind of shot-blast apparatus electric control system, comprise a grating scale for detection of Workpiece length, the PLC being connected with grating scale, multiple relays that open and close for controlling shot-blast apparatus motor that are connected with PLC, described PLC connects its keying of leakage sand valve control of shot-blast apparatus; Described motor comprises ramming head motor, reclaims blower fan, lifting motor, helical feed motor and separation vessel motor, the boot sequence that PLC sends motor and leakage sand valve is: reclaim blower fan → lifting motor → helical feed motor → separation vessel motor → ramming head motor → leakage sand valve, the shutdown signal of equipment behind ball blast district is contrary with above-mentioned boot sequence.
The invention has the beneficial effects as follows: the length that automatically detects workpiece by increasing grating scale; Realize the interlock of ramming head motor, recovery blower fan, lifting blower fan, helical feed motor, separation vessel motor, leakage sand valve, carrier chain, grating scale; The actual job time that shortens shot-blast apparatus motor, makes it approach effective operation time, eliminates the motor dry run in the stand-by period, thereby promotes the Shot Blasting System life-span, reduces the loss of energy consumption and ball material.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further;
Fig. 1 is principle of the invention block diagram;
Fig. 2 is workflow diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of shot-blast apparatus electric control system has a grating scale for detection of Workpiece length, the PLC being connected with grating scale, multiple relays that open and close for controlling shot-blast apparatus motor that are connected with PLC, described PLC connects its keying of leakage sand valve control of shot-blast apparatus; Described motor comprises ramming head motor, reclaims blower fan, lifting motor, helical feed motor and separation vessel motor, the boot sequence that PLC sends motor and leakage sand valve is: reclaim blower fan → lifting motor → helical feed motor → separation vessel motor → ramming head motor → leakage sand valve, the shutdown signal of equipment behind ball blast district is contrary with above-mentioned boot sequence.
Described grating scale is arranged on the front station of shot-blast apparatus, and described grating scale and carrier chain interlock, automatically detect the length of workpiece, and send ball blast activity duration signal to PLC.Described carrier chain is gathering chain or self-propelled hoist or suspended chain or skid, possesses frequency conversion function.
As shown in Figure 2, speed of travel V1 under carrier chain ball blast waiting status, grating scale sensitive time (workpiece is by the time of grating scale) T1, the length L 1=V1*T1 of detected workpiece, and automatically by its data feedback to PLC, PLC analyzes the difference of Workpiece length L1 and standard design Workpiece length L0, in conjunction with the speed of travel V2 under carrier chain ball blast state, calculate practical work piece and reclaim fan delay time T2=(L0-L1)/2V2, and after reclaiming the rear time delay T2 of fan starting time T 0 second, design workpiece opens recovery blower fan, and trigger other motors and leak sand valve and start by above-mentioned boot sequence, after leaking sand valve opening, start timing, after practical work piece ball blast time T 4=(L1+L2)/V2 (L2 is ball blast compartment body length), leak sand valve closing, and trigger other motors according to motor shutdown signal orderly close-down motor.Because dust after ball blast is larger, after lifting motor is closed, close recovery blower fan after waiting for a setting-up time, all the other motors cut out one by one according to another setting-up time, have optimized the shut-in time of each equipment motor.Practical work piece reclaims fan starting time T 3=T0+T2.
In the present embodiment, after lifting motor is closed, wait for that 1min closes recovery blower fan, all the other motors cut out one by one according to the interval of 2s.
The course of work: enter after shot-blast apparatus until the workpiece of ball blast, the operation of shot blast room door motor, close shot blast room door, according to the workpiece data of the speed of travel of carrier chain and grating scale feedback, when workpiece runs to specific position, induction system sends " enabling signal " automatically to reclaiming blower fan, reclaim blower fan and receive startup automatically after " enabling signal ", successively enabling signal is sent to follow-up station motor, sending order is: reclaim blower fan → lifting motor → helical feed motor → separation vessel motor → ramming head motor → leakage sand valve.Workpiece is by behind ball blast region, and according to each motor of contrary orderly close-down, concrete order is for leaking sand valve → ramming head motor → separation vessel motor → helical feed motor → lifting motor → recovery blower fan.
The present invention accomplishes shot-blast apparatus associated motor in workpiece effective operation time, leaks the running of sand valve intelligence, and in parts waiting time, intelligence is shut down, and the actual ball blast time of workpiece is corresponding with the size of workpiece.
